CARPET-SWEEPER.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed March 18, 1918. Serial No. 223,160.

To all whom it may concern:

Be it known that I, CLARENCE D. SAR GENT, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have in vented a certain new and useful Improvement in Carpet-Sweepers, of which the following is a description, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

My invention relates to carpet-sweepers,

and is more particularly an improvement on the carpet-sweeper.

The object of this invention is to provide an improved means for brush adjustment, whereby the brush may be adjusted vertically, and whereby it may engage the carpet more or less deeply, according to the texture thereof. Such adjustment provides for the variations in the amount of nap, on the various kinds of carpets or rugs.

Broadly speaking, adjustable bearings for the brush are not new, but my invention consists more particularly in an adjustment for the type of sweeper set forth in accompanying drawings, in which the case is provided with an end band, the brush with end sockets, a fiat spring piece lying along between said band and wheels carries a pin entering said socket.

More particularly the invention consists in provision for the turning of a thumbscrew, one way or the other, to vary the vertical position of the brush, with means of holding the spring piece securely in the position to which it may be moved.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a horizontal sectionof a portion of a. carpet sweeper embodying my invention: Fig 2, is a side view: and Fig. 3, is an end view, both sides of the machine being similar. The end band is shown at 6, and a is the spring piece, which is riveted at 5 to the end band.

Copies of this patentmay be obtained for five cents each, by addressing the "Commissioner of Patents,

The spring piece carries the pin 3, which enters socket 2, in the end of brush, the other end of spring piece 4 is riveted to lower end of bar 7 the upper end of bar 7, is riveted to lever 8, at 17, lever 8 is riveted in the center to hanger 9, by rivet 16, said hanger is mounted on said case. At the other end said lever 8, is connected to nut 11 by a joint, nut 11 is fitted to thumbscrew bolt 12, thumbscrew bolt 12, is mounted on hanger 10, so as to turn but not to move up or down. If thumbscrew bolt 12, is turned one way or the other as the case may be, it will move the brush up or down; and thereby hold the brush in a new position. If desired to remove brush, spring piece 4 must be pulled out with band 6 as in the old way to release pin 3.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:

In a carpet sweeper, the combination of a case, a brush provided with end sockets and members carrying pins to be received into said sockets, said members having one end pivotally connected to the case, the other end of said members being connected by hinge joints to the lower ends of shorter members, the upper ends of said shorter members being pivotally connected to the if outer ends of levers mounted on the top of said case, said levers being pivoted at their centers in hangers, so that each end of said levers can tilt up or down, the inner ends of said levers being connected to a threaded,

nut at the center of said case, said nut being adapted to run on a threaded thumbscrew, said thumbscrew being perpendicularly supported by a swivel connection with the casing.

In testimony whereof I have affixed my signature.

CLARENCE D. SARGENT.
